This article introduces the relevant knowledge of "how to insert a new Activity in Android". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

There are three steps to insert a new Activity:

1. Create a new Activity program code. Here, take "new.class" as an example.

2. Add the description of the new Activity to AndroidManifest.xml

3. Call the original Activity to start the new Activity

Step by step, first create a new Activity program code:

Right-click on package under src in Package Explorer on the left side of Eclipse, and New a Class. It is important to note that in the pop-up dialog box, Superclass must uppercase to select Activity,Name (this is the rule of JAVA, it must be, otherwise it cannot be created)

Insert the code into the newly created Name.class

Public class Name extends Activity {@ Override protected void onCreate (Bundle savedInstanceState) {/ / TODO Auto-generated method stub super.onCreate (savedInstanceState); setContentView (R.layout.newviewxml);}}

Then the corresponding xml file describing UI is established.

Right-click project/res/layout, and under layout, new- > Android xml file

Just copy the format of the original main.xml. According to the above code (R.layout.newviewxml), the xml file name should be newviewxml.xml.

Next step 2, add a description of the new Activity to the AndroidManifest.xml

Open AndroidManifest.xml, switch to the Application page, and in Application Nodes, list all the current Activity of the program (except the one we are going to add now, of course), and click the Add on the right, as shown in the figure:

Click OK, open AndroidManifest.xml, and join

Then call the old Activity to start the new Activity

Intent intent=new Intent (); intent.setClass (Test.this,Name.class); / / the current Activity is Test and the target Activity is Name / / the data is passed to the new Activity starting from the following line. If no data is passed, it is just a simple jump. Please comment out Bundle bundle=new Bundle () bundle.putString ("key1", "value1"); / / key1 is named, and value1 is the value bundle.putString ("key2", "value2"); intent.putExtras (bundle) / / end of data transfer startActivity (intent)

At this point, the new Activity is called. If you just transferred the data in the original Activity, you can get it in the new Activity with the following code.

Bundle bundle=this.getIntent (). GetExtras (); String s1=bundle.getString ("key1"); String s2=bundle.getString ("key2"); "how to insert a new Activity in Android". Thank you for reading.
